Computer/PC connection
Many notebooks do not turn on their external video ports when connected to a projector.
Usually a key combo like FN + F3 or CRT/LCD key turns the external display on/off. Locate a
function key labeled CRT/LCD or a function key with a monitor symbol on the notebook. Press
FN and the labeled function key simultaneously. Refer to your notebook's documentation to find
your notebook's key combination.
